v impacts in the practical use of the same.

And the present improvement has for its object to provide a structural formation of the annular rebound ring of striking bag supports, of a durable and economical form, possessing the necessary resiliency to eflect a rapid rebound of the striking bag, and with which an effective and substantial attachment is attained between the ring and the usual overhanging frame which carries the same, all, as will hereinafter more fully appear.

In the accompanying drawings Figure 1, is a perspective view illustrating the general arrangement of parts. Fig. 2, .is a plan view of the rebound ring and its supporting spider. Fig. 3, is an enlarged detail section on line wm,-Fig. 2.

Similar reference numerals indicate like parts in the several views. I

Referring to the drawings, 1 designates the usual overhanging bracket or frame work, to which the rebound ring 2 and its carrying spider 3 is fixedly attached, the center of said spider being provided with a depending coupling head 4 for the attachment of the supporting cord of a striking bag;

In the present improvement, the rebound Patented June 6,1916.

ring 2 is formed of a flat band of resilient h material, such as spring steel,.with its lower end formed into a rounded angularly disposed flange 5, preferably of the inturned form shown in Figs. 1, 2 and 8. The rounded annular portion thus formed, constitutes the impact surface for the striking bag in actual use, and is adapted to receive the impacts without any wear upon the material of the bag.

6 designates a plurality of circularly spaced folds or flanges formed in the upper marginal portion of the rebound ring 2 and adapted to diminish the height of said ring at such-points and thereby lmpart additional resiliency to the parts of said ring intermediate said folds or flanges 6. The main purpose is however to provide means for efi'ecting a substantial attachment of the rebound ring 2 to the ends of the carrying spider 3 by means of vertical screws or bolts 7, as illustrated in Fig. 3;

Having thus fully described my said in- I vention, what I claim as new and desire to secure by Letters Patent, is

1, A rebound ring for striking bag supports, consisting of 'a flat band ring having a rounded flange at its lower margin and a plurality of circularly spaced folds or flanges in its uppermargin, substantially as set forth.

2. A rebound ring for striking bag supports, consisting of a flat hand ring having a rounded inturned flange at its lower margin, and a plurality of circularly spaced folds or flanges in its upper margin, substantially as set forth.
